Question
Chapter 10.14, Problem 21P
Interpretation Introduction
Interpretation:
The class of compound for the given absorption band has to be given.
Concept Introduction:
IR spectroscopy is concerned with the study of absorption of infrared radiation, which causes vibrational transition in the molecule.
IR frequency (cm-1): It is the number of wave crests that pass by a given point in one second frequency has units of hertz (Hz).
Wavelength: I t identified the distance from any point on one wave to the corresponding point on the next wave, or its wavelength is generally measured in nanometers (1 nm=10-9 m).

Absorption bands in the region of 1600-1700 cm-1 are often used for quantification of caffeine. What does the bands in this region refer to?
A ketone possesses an absorption band with peak centered around 1710 cm-1, from the information deduce a value for the force constant of the C=O double bond.

12D.15 At low resolution, the strongest absorption band in the infrared
absorption spectrum of 12C160 is centred at 2150 cm-¹. Upon closer
examination at higher resolution, this band is observed to be split into two
sets of closely spaced peaks, one on each side of the centre of the spectrum at
2143.26 cm-¹. The separation between the peaks immediately to the right and
left of the centre is 7.655 cm¹. Make the harmonic oscillator and rigid rotor
approximations and calculate from these data: (a) the vibrational wavenumber
of a CO molecule, (b) its molar zero-point vibrational energy, (c) the force
constant of the CO bond, (d) the rotational constant B, and (e) the bond
length of CO.
